parse_ini_file — Parse a configuration file
$filename
[, bool $process_sections = FALSE
[, int $scanner_mode = INI_SCANNER_NORMAL
]] ) : array
parse_ini_file() loads in the
ini file specified in filename,
and returns the settings in it in an associative array.
The structure of the ini file is the same as the php.ini's.
filenameThe filename of the ini file being parsed.
process_sections
By setting the process_sections
parameter to TRUE, you get a multidimensional array, with
the section names and settings included. The default
for process_sections is FALSE
scanner_mode
Can either be INI_SCANNER_NORMAL (default) or
INI_SCANNER_RAW. If INI_SCANNER_RAW
is supplied, then option values will not be parsed.
Începând cu PHP 5.6.1 poate de asemenea fi specificat ca
INI_SCANNER_TYPED. În acest mod tipurile boolean, null și
integer sunt păstrate, când este posibil. Valorile string "true",
"on" și "yes" sunt convertite în TRUE.
"false", "off", "no" și
"none" sunt considerate FALSE. "null"
este convertit în NULL în modul cu tipuri. De asemenea toate șirurile numerice
sunt convertite în integer, dacă acest lucru este posibil.
The settings are returned as an associative array on success,
and FALSE on failure.
| Versiune | Descriere |
|---|---|
| 7.0.0 | Hash marks (#) are no longer recognized as comments. |
| 5.6.1 |
Added new INI_SCANNER_TYPED mode.
|
| 5.3.0 |
Added optional scanner_mode parameter.
Single quotes may now be used around variable assignments.
Hash marks (#) should no longer be used as comments
and will throw a deprecation warning if used.
|
| 5.2.7 |
On syntax error this function will return FALSE rather than an empty
array.
|
| 5.2.4 | Keys and section names consisting of numbers are now evaluated as PHP integers thus numbers starting by 0 are evaluated as octals and numbers starting by 0x are evaluated as hexadecimals. |
Example #1 Contents of sample.ini
; This is a sample configuration file ; Comments start with ';', as in php.ini [first_section] one = 1 five = 5 animal = BIRD [second_section] path = "/usr/local/bin" URL = "http://www.example.com/~username" [third_section] phpversion[] = "5.0" phpversion[] = "5.1" phpversion[] = "5.2" phpversion[] = "5.3" urls[svn] = "http://svn.php.net" urls[git] = "http://git.php.net"
Example #2 parse_ini_file() example
Constants may also be parsed in the ini file so if you define a constant as an ini value before running parse_ini_file(), it will be integrated into the results. Only ini values are evaluated. For example:
<?php
define('BIRD', 'Dodo bird');
// Parse without sections
$ini_array = parse_ini_file("sample.ini");
print_r($ini_array);
// Parse with sections
$ini_array = parse_ini_file("sample.ini", true);
print_r($ini_array);
?>
Exemplul de mai sus va afișa ceva similar cu:

[one] => 1
[five] => 5
[animal] => Dodo bird
[path] => /usr/local/bin

Example #3 parse_ini_file() parsing a php.ini file
<?php
// A simple function used for comparing the results below
function yesno($expression)
{
return($expression ? 'Yes' : 'No');
}
// Get the path to php.ini using the php_ini_loaded_file()
// function available as of PHP 5.2.4
$ini_path = php_ini_loaded_file();
// Parse php.ini
$ini = parse_ini_file($ini_path);
// Print and compare the values, note that using get_cfg_var()
// will give the same results for parsed and loaded here
echo '(parsed) magic_quotes_gpc = ' . yesno($ini['magic_quotes_gpc']) . PHP_EOL;
echo '(loaded) magic_quotes_gpc = ' . yesno(get_cfg_var('magic_quotes_gpc')) . PHP_EOL;
?>
Exemplul de mai sus va afișa ceva similar cu:
(parsed) magic_quotes_gpc = Yes (loaded) magic_quotes_gpc = Yes
Notă:
This function has nothing to do with the php.ini file. It is already processed by the time you run your script. This function can be used to read in your own application's configuration files.
Notă:
If a value in the ini file contains any non-alphanumeric characters it needs to be enclosed in double-quotes (").
Notă: There are reserved words which must not be used as keys for ini files. These include: null, yes, no, true, false, on, off, none. Values null, off, no and false result in "", and values on, yes and true result in "1", unless
INI_SCANNER_TYPEDmode is used (as of PHP 5.6.1). Characters ?{}|&~!()^" must not be used anywhere in the key and have a special meaning in the value.
Notă:
Entries without an equal sign are ignored. For example, "foo" is ignored whereas "bar =" is parsed and added with an empty value. For example, MySQL has a "no-auto-rehash" setting in my.cnf that does not take a value, so it is ignored.
